### My Question

I am trying to capture images from a realsense camera using the realsense package, and not the open3d::t::io::RealSenseSensor. the reason is that there are more configurable options such as aligning the images to the depth and not the color images, and more.

and so i want to do this:
m_pipeline = rs2::pipeline();
auto frame = m_pipeline.wait_for_frames();
auto rgbImageData = frame.get_color_frame();
auto depthImageData = frame.get_depth_frame();

//I would like there to be a constructor of some sort like this...
open3d::geometry::image depthOpen3dImage = open3d::geometry::image(depthImageData.get_data());
open3d::geometry::image rgbOpen3dImage = open3d::geometry::image(rgbImageData.get_data());

how can i do this?
